The analysis of spinal alignment, balance and muscular strength of lower extremity between gymnasts and freestyle snowboarders
The purpose of this study is to compare spinal alignment, balance and muscular strength of lower-extrimity between gymnasts and freestyle snowboarders. This study measured trunk imbalance, pelvic tilt, pelvic torsion, lateral deviation, kyphotic angle, lordotic angle and the abilities of balance on each level and knee extension, flexion and ankle plantar flexion, dorsiflexion on each angular speed with 10 male gymnasts and 7 male freestyle snowboarders. The abilities of balance was measured every 3 times in 20 seconds on level 12(easy), level 6(hard), and level 1(very hard). Knee isokinetic muscular strength was measured 5 times, 5 times on the angular speed 60°/sec, 180°/sec respectively. Ankle isokinetic muscular strength was measured 5 times on the angular speed 60°/sec. Spinal alignment was measured by Formetric III, balance by Biodex stability System, and muscular strength by HUMAC. Statistical results were calculated by SPSS/PC Window version 16.0. It was analyzed by Independent 𝑡-test. The statistical level of significance was set to 𝑝<.05. 1. Snowboarders' lordotic angle was statistically higher than gymnasts'. 2. The difference between both groups were not significant on level 12(easy), level 6(hard), and level 1(very hard) tests. 3. Gymnasts' ankle plantar flexion, and dorsiflexion on the angular speed 60°/sec were denoted statistically higher than those of snowboarders. As a result, the spinal alignment of both groups were similar and both groups had excellent sense of balance. However, snowboarders' spine was bended slightly more than gymnasts' on forward direction. Snowboarders' knee and ankle muscular strength was significantly worse than gymnasts'. If gymnast's training program is applied to snowboarder, it will result in positive effects such as improvement on performances and skills.
